Description

Method, system and server for feeding back state of receiver

Technical field

The present invention relates to the field of communications technologies, and in particular, to a method, system, and server for feeding back a state of a receiving end.

Background technique

The development of mobile communication technology is changing with each passing day. Especially since the advent of the third generation mobile communication technology (3G), new services have emerged one after another. Since the advent of wireless terminals, Short Message Service (SMS), one of the basic functions of wireless terminals, has been one of the most frequently used services for mobile communication device owners.

However, when users use short message service, they often encounter the following situation: User A sends a short message to user B, but user B may fail to reply to user A in time due to downtime, shutdown, no network signal, etc. At this time, user A wants to automatically obtain the current state of user B. At this time, the network side needs to automatically feed back the current state of User B to User A.

In the current SMS technology, a successful SMS sending and receiving process is as follows: The Mobile-Services Switching Center (MSC) receives a Transport Protocol Data Unit (Mobile Protocol Data Unit) from the mobile terminal MS (Mobile Station) A. TPDU), query the Mobile Location Integrated Services Digital Network (MSISDN) number corresponding to the MSA to the Visit Location Register (VLR), and insert it into the Protocol Data Unit (PDU), and then transmit it to the Interworking MSC for SMS (Internetworking) MSC for SMS, SMS-IWMSC). The MSC returns a report to the MS based on the processing result. The SMS-IWMSC receives the TPDU from the MSA from the MSC, checks the validity of the SC address as the TPDU transmission destination, and then transmits the TPDU to the Short Message Center SC (Service Centre). The SMS-IWMSC returns 4 reports to the MSC according to the processing result. .

After receiving the TPDU, the gateway MSC (Gateway MSC for SMS, SMS-GMSC) for the SMS receives the TPDU from the SC, performs parameter check, and requests the HLR to perform service authentication and query the routing information of the MSA. After normal, the PDU is routed. To the MSC. SMS-GMSC base The result is returned to the SC report. After receiving the TPDU from the SMS-GMSC, the MSC queries the VLR for the MSB information, such as the location area information, to transmit the SMS to the MSB according to the query result. And the MSC returns a report to the SMS-GMSC according to the processing result.

Therefore, after the SC successfully forwards the information sent by the MSA, it sends a status report to the MSA to inform the terminal that the short message has been successfully forwarded. However, after the SC forwards, whether it successfully reaches the MSB. If the MSB does not reply to the information, then the current state of the MSB is not, and the information network side does not give feedback to the MSA. Therefore, it is necessary to study a method of feeding back the current state of the receiving end of the short message. Summary of the invention

The method and system for feeding back the state of the receiving end of the present invention, the function of the state of the feedback receiving end is opened by the server for the first terminal; so that the server can automatically feed back the current state of the receiving end to the server when the receiving end is down, shut down, not registered, and the like. The first terminal.

As shown in FIG. 1 , it is a flowchart of an embodiment of a feedback receiving state method according to the present invention, where the method includes:

Step 101: The server is configured to enable a state of the feedback receiving end of the first terminal. Step 102: After receiving the short message sent by the first terminal, the server sends the short message to the receiving end. If the short message is received, the short message sent by the receiving end to the first terminal is not received within the preset time. Then, the server acquires the current state of the receiving end, and feeds back to the first terminal.

Specifically, if the server does not receive the feedback information of the short message on the receiving end, or receives the feedback information sent by the receiving end, and the destination address is not the first terminal, the server automatically acquires the current state of the receiving end, and feeds back to the first terminal.

If the server receives the second information of the receiving end, it determines that the short message of the first terminal successfully arrives at the receiving end.

The above server can be located in the short message center.

In the foregoing step 101, the process for the server to enable the function of the feedback receiver state for the first terminal is as shown in FIG. 2, and the process specifically includes:

Step 201: The first terminal initiates a request for enabling the function to the short message center.

Step 202: The short message center receives the request.

Step 203, the short message center to the home location register (HLR) to query whether the mobile phone registered the function, and if so, step 204; if not registered, step 205;

If the first terminal registers the function, you can choose to activate (that is, start the function successfully) or temporarily disable the function (the function will not be activated temporarily), but if the first terminal does not register the function, the function cannot be activated. , that is, the function cannot be successfully started.

Step 204: The short message center accepts the request, registers the number of the first terminal, and feeds back the success information;

Step 205: The SMS center rejects the request and feeds back a failure message.

After successfully starting the function, the first terminal may include its identification information in the information sent by the first terminal to the server.

In the short message protocol specification, TPUD is defined as a protocol data unit that directly carries short message application layer data transmitted between an MS and an SC. TPUD—a total of six types are: short message (SM-DELIVER), short Message service sending SMS (SMS-DELIVER-REPORT), submitting short message (SM-SUBMIT), short message service submission report (SMS-SUBMIT-REPORT), SMS-COMMAND and SMS-STATUS-REPORT.

SM-SUBMIT is a kind of TPDU in the MS->SC direction. The basic information elements include: short message type identifier of the transmission protocol (ΤΡ-ΜΉ), TP-RD (representing whether the short message center repeatedly receives the same sending address and receiving) Address SMS), TP-VPF (indicating whether the validity period is valid), TP-RP (indicating that an answer path is required), TP-UDHI (indicating that the TP-UD field contains header information), TP-SRR (indicating whether status report is required) , TP-MR (indicating the transmission of short messages), TP-DA (representing the address of the target SME), TP-PID (representing the protocol of the upper layer), TP-DCS (representing the encoding method of user data), TP-VP ( Indicates the short message validity period), TP-UDL (representing the length of user data), and TP-UD (representing user data, ie, short message content). These information elements define what information is included in the TPDU of the MS to the SC direction, such as TPUD type, short message destination address, etc., in order to distinguish from these information elements, a new information element is defined in the SM-SUBMIT information element: TP-SRTR, which is used to identify whether the information sent by the terminal to the SC is activated. The function of feeding back the state of the receiving end; that is, the TP-SRTR is the identification information mentioned in the foregoing method embodiment; of course, those skilled in the art can also implement the function by adding other new information elements, the TP in this embodiment. -SRTR is only an example.

Combined with the analysis of the above SM-SUBMIT information element, Fig. 3 shows a schematic diagram of the capability format provided by the present invention.

As shown in FIG. 4, the source terminal of the present invention provides a flow chart for sending a short message to a short message center. The MS mentioned in this embodiment is a source terminal, and the process includes:

Step 401: The MS sends a short message to the MSC.

The short message may include: SMS content, destination SC address, and identification information of whether to activate the function of the feedback receiver state;

Step 402: The MSC queries the VLR whether the MS can send a short message.

Step 403: The VLR feeds back related information to the MSC.

If the MS can send a short message normally, the MSISDN number is provided;

Step 404: If the MS can normally send the short message, the MSC forwards the short message to the IWMSC. The short message includes the SMS content, the MSISDN number of the source MS, the destination SC address, and Whether the source MS activates this function.

Step 405: The IWMSC forwards the short message to the SC.

The short message includes the SMS content, the MSISDN number of the first terminal, the destination SC address, and whether the first terminal MS activates the function.

At this point, the SC successfully receives the short message sent by the first terminal. It should be noted that the SC needs to record whether the first terminal starts the function, and the time A of the short message of the first terminal arrives at the SC.

After successfully receiving the short message sent by the first terminal, the SC may send the short message to the receiving end (the destination terminal). As shown in FIG. 5, the short message center provided by the present invention sends the short message to the destination terminal. Flowchart, the process includes:

Step 501: The SC sends a short message to the gateway mobile switching center (GMSC).

Step 502: The GMSC queries the HLR to which the destination terminal belongs to query routing information.

Step 503: The HLR returns a confirmation message.

If the query is successful, the routing information includes the MSC number where the destination MS is located, and the International Mobile Subscriber Identity (IMSI) and the Local Mobile Subscriber Identity (LMSI) of the destination terminal user. Step 504: The GMSC sends a short message to the MSC.

The GMSC needs to send a short message to the destination MSC according to the obtained routing information, which includes the SMS content, the source SC address, the IMSI or the LMSI of the destination MS;

Step 505: The MSC queries the VLR for related information of the destination MS.

Step 506: The VLR returns an acknowledgement information to the MSC.

Step 507: The MSC forwards the short message to the destination MS.

At this point, the SC successfully forwards the short message sent from the source MS (first terminal) to the destination MS (receiver).

In addition, the embodiment in which the source terminal sends a short message to the short message center and the short message center send the short message to the destination terminal may be combined into one embodiment, that is, the short message center sends the short message of the source terminal to the destination terminal. example.

After the SC successfully forwards the short message sent from the source MS to the destination MS, it needs to go to the source MS. If the short message has been successfully sent to the destination MS, if it does not arrive successfully, the source MS needs to feed back the current state of the destination MS.

In the embodiment in which the mobile terminal sends the short message to the short message center, if the information element sent by the source terminal includes the identification information of the function of successfully starting the feedback receiving state, the SC receives the short message sent by the source terminal. Record the time of arrival of the short message TimeA and the source terminal number. Thus, if the source terminal still does not reply to the information at the current time -TimeA>TimeB, the SC starts to obtain the current state of the target MS; wherein, TimeB is a preset time, and the preset time can be dynamically adjusted according to needs.

As shown in FIG. 6, a flowchart of an embodiment of a current state of a destination terminal provided by a short message center according to the present invention includes:

Step 601: The SC initiates a query request to the MSC to which the destination terminal belongs.

The SC may initiate a query request to the home MSC of the destination terminal according to the MSC number of the destination terminal in the HLR routing information, where the request includes the source terminal number and the destination terminal number;

Step 602: The MSC to which the destination terminal belongs queries the VLR for the current state of the destination MS. The VLR stores the dynamic information and status information of the user, and the subscription information of the user downloaded from the HLR. When the MSC queries the relevant information of the destination MS, the VLR can report the related information to the MSC. The related information includes whether the MS has subscribed to the SMS service, whether it has roamed, whether it has been shut down, and whether it has been down.

Step 603: The VLR feeds back the current state of the destination MS to the MSC to which the destination terminal belongs. Step 604: The MSC to which the destination terminal belongs sends the current state of the target MS to the SC.

At this point, the SC has acquired the current state of the destination MS, after which the SC can forward the current state of the obtained destination MS to the source MS. As shown in FIG. 7, the short message center provided by the present invention feeds back the current state of the destination terminal to the source terminal, and the process includes:

Step 701: The SC feeds back the current state of the obtained destination terminal to the MSC corresponding to the source terminal. After acquiring the current state of the destination terminal, the SC feeds back the current state, the destination terminal number, and the source terminal number of the destination terminal to the source terminal. MSC;

Step 702: The MSC corresponding to the source terminal feeds back the current state of the destination terminal to the source terminal. After receiving the information sent by the SC, the MSC corresponding to the source terminal feeds back the current state of the destination terminal to the source terminal according to the source terminal number.

At this point, the SC completes forwarding the current state of the destination terminal to the source terminal.

In addition, the embodiment in which the short message center obtains the current state of the destination terminal and the short message center feed back the current state of the destination terminal to the source terminal may be combined into an embodiment, that is, the short message center acquires the current state of the destination terminal, and Return it to the embodiment of the source terminal.

It should be noted that the first terminal in this embodiment is the source terminal, and the receiving end is the destination terminal. The method for feeding back the state of the receiving end of the present invention enables the server to open the state of the feedback receiving end state for the first terminal, so that the server can obtain the current state of the receiving end and feed back to the first terminal when the receiving end is down, shut down, or not registered. .
